BUG(?): mailing list archive formatting
by Jim 01 Sep '24

01 Sep '24

To whomever might be able to do something about this: The "quoting" on the mailing list archive seems to have a bug. For example, in https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/NZOIVLVPZHHM… in Hans' response of 27 Aug 1:07 a.m., it has "There are three ways" attributed to contact(a)0vladimirgrbic.com, whereas in the email I received those four words (appear to) come from Hans. Is this something that someone can (and cares to) fix? Cheers. Jim

registers in footnotes as page glossaries
by Pablo Rodriguez 31 Aug '24

31 Aug '24

Hans, I wonder whether MkXL may have page registers for footnotes. This would be great to have page glossaries, such as in https://geoffreysteadman.com/wp-content/uploads/2017/08/lysiascrito-24aug17… (first apparatus). To be fair, I have asked that a while ago (with MkIV). It would be great to have these page glossaries as language aids. Right now, they need to be composed manually (using a word processor, no TeX). Many thanks for your help, Pablo

Hi, I have plotted a log function and I want to draw an xy axis grid. Below is the code \starttext \startMPcode draw function(1,"x", "log(x)", .1, 10, .01) scaled 1cm; for i = 0 upto 10: draw (i*cm, -5cm) -- (i*cm, 5cm) dashed; endfor; for i = -5 upto 5: draw (0, i*cm) -- (10cm, i*cm) dashed; endfor; \stopMPcode \stoptext My first for loop draws lines but the second gives me an error. Please help. -- Respect, Shiv Shankar Dayal

BUG REPORT: Italic Correction in ConTeXt LMTX
by contact＠vladimirgrbic.com 30 Aug '24

30 Aug '24

Hello, I started using ConTeXt LMTX 2 days ago and after some initial testing I noticed an unexpected behavior regarding italic correction. In short, I cannot seem to produce italic correction like I could in plain TeX or even LaTeX. I've asked the question on TeX StackExchange and another user confirmed the suspicion in his answer. I would suggest you take a look at it because the formatting of the question and the answer is prettier than in this plain text email. Furthermore, a person who provided the answer already did some research. See the question here: https://tex.stackexchange.com/questions/724568/how-to-invoke-italic-correct… Here is what I observed: Compare the kerning produced in between 'r' and 'p' in the word "airport" when italic correction is applied in plain TeX (compiled with `pdftex`) and in ConTeXt LMTX (compiled with `luametatex`). Here are the minimal working examples. Plain TeX ``` airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \bye ``` ConTeXt LMTX ``` \starttext airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \stoptext ``` Please confirm if this, in fact, is the issue/bug or if I am not approaching this correctly. I am brand new to ConTeXt, so it could be me. Thank you in advance! Vladimir

Defining mathsymbols from unicode char
by Jethro Djan 29 Aug '24

29 Aug '24

Dear all, 1. I am trying to define the "pitchfork" unicode character( https://unicodeplus.com/U+22D4) to use in ConTeXt as stated on page 387 of new math manual authored by Hans and Mikael: \definemathsymbol[pitchfork][relation]["22D4] It works with some unicode characters and not others (like this character). What can I do to make it work? 2. I would like a \not\perp symbol but it doesn't draw the stroke on top of the symbol. I know you could manipulate this in a plain TeX but I am thinking the mechanism in ConTeXt would be different. How can I achieve this? Also how can I get the \notperp symbol in the accepted answer of https://tex.stackexchange.com/questions/27651/symbol-about-not-orthogonalit… ? Thanks. Jethro

MetaPost dirtree?
by Henning Hraban Ramm 29 Aug '24

29 Aug '24

Hi, did someone already create directory trees with MetaPost? It should be quite easy, but I couldn’t find examples and was thinking about porting the LaTeX dirtree package (i.e. look at the code and try to implement something similar in Lua and MP). I have ideas… (but I have always too many of them). So far, I used the output of `tree`, and that’s not really beautiful. Hraban

Help with Metapopst code
by Shiv Shankar Dayal 28 Aug '24

28 Aug '24

Hi, Consider following code: vardef polygon_with_side(expr n, s) = save a, b, r; numeric a, b, r; a * n = 360; a + 2b = 180; r = s * sind(b) / sind(a); for i = 0 upto n-1: (0, r) rotated (a * i) -- endfor cycle enddef; beginfig(1); path p; p = polygon_with_side(21, 20); draw p; endfig; bye; It draws a polygon with 21 sides with radius 20. I understand all of it except the for loop. What is (0, r) rotated (a *i) doing? -- Respect, Shiv Shankar Dayal

Is there a way to apply withpattern to text, like fillcolor in lmt_outline[].
by ai2472206007＠yeah.net 28 Aug '24

28 Aug '24

hi , Is there a way to apply withpattern to text, like fillcolor in lmt_outline[]. what I envisaged: https://imgse.com/i/pAAkfjf I've found someone who has asked a similar question, just a combination of the two functions : lmt_outline[] and lmt_shade[] in that question. question from https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/D5GBGF3RXN75… However, this example didn't work successfully on the Mac, it just showed a background color block.
